ROOF-JOINT.

Specification otLetters Patent. P tent d May it, 1910.

Application filed June 10, 1909 Serial No. 501,320.

It is the object of the present invention to provide a joint of the kind stated which'is simple and-reliable, and which can be quickly and easily made.

Another object of the invention is to provide a joint structure which can be applied to any slope of roof.

The invention is illustrated panying-drawing in Which- Figure 1 is a vertical sect-ion. Fig. 2 is an elevation, partly in section, of the calking sleeve to-be hereafter described, and

Fig. 3 is an inverted plan view of a fragment thereof,

Referring more particularly to the drawing, 5 denotes a frusto-conical collar, to the lower edge or base of which is secured an outstanding flange 6 whereby the collar is secured to the roof (not shown), said lower edge being cut at a slant to correspond to the slope of the roof to which it is applied; The soil or other pipe 7 passes through this (-ollar,.and extends to any desired height above the same.

()n the upper edge of the collar 5 is supported a calking sleeve 8 whichis made of lead or some other soft malleable metal or alloy. The sleeve is frusto-conical in shape,- and has adjacent to its base an internal shoulder 9 which seats on the upper ,edge of the collar whereby the sleeve is held in place thereon. The pipe 7 also passes through the sleeve at .a close fit wlth the upper or contracted end thereof.

end into still closer contact with the roof of a building, and it 'con-' in the accom- In assembling the joint, the device is slipped down over the pipe 7 and. secured to the roof'by means of the flange 6. The

conical. shape of the sleeve 8 permits this to be readily done. The upper end of the sleeve fits quite snugly around the pipe, but a stillcloser joint is made by forcing said the pipe. Inasmuch as the sleeve is malleable, and the pipe is spaced from the, major portion there of, as well as from the collar 5, the entire device can be set atmlifi'erent angles to the pipe after it is slipped over the same as 'stated, "to conform to the pitch or slope of the roof. It will, be noted that the lower end .of the sleeveexteriorly surrounds the upper end of the collar, in view of which it will shed rain and prevent the same from entering at this point. The sleeve is tapered in thickness in the direction of its upper end, which makes --it thin at thls end, and more pliable, and, consequently, more readily hammered around the pipe. It will also yield more readily to permit the hereindescribed adjustment,

I claim:

A roof joint comprising a collar having means for attachment to the roof, and

adapted to inclose a pipe, a frusto-conical' calking sleeve of malleable material exteriorly surrounding and supported on the upper end of tli e'collar, said sleeve being conical on its interior, and tapered in thickness in the direction of its upper end, to fit the pipe and to be forced down thereon, said pipe being spacedfrom the collar and from the major portion ofthe sleeve suthciently to permit the collar to be set at different angles to the pipe, and the sleeve being adapted to have its upper end forced into still closer contact with the pipe.

In testimony whereof I affix my signature in presence of two witnesses.
